SNGA120408 DX140 ISO turning indexable insert by Tungaloy — PCD grade for aluminium

The SNGA120408 DX140 is an ISO‑standard, square turning indexable insert designed for external and internal turning of aluminium and non‑ferrous materials, featuring a 90° geometry and a 0.8 mm corner radius.

• SNGA120408 DX140 PCD for aluminium and non‑ferrous metals
• ISO‑standard square insert, 90° with 0.8 mm radius
• Cylindrical hole for secure clamping
• Long tool life and high cutting speeds

High-speed cutting and material suitability for efficient turning

The polycrystalline diamond (PCD) cutting material of this indexable insert offers exceptionally low wear rates when machining softer but abrasive alloys such as aluminium and other non‑ferrous metals. The combination of a PCD cutting edge on a carbide body enables significantly higher cutting speeds and longer tool life than conventional carbide grades when used in the recommended materials. This means fewer tool changes, reduced downtime and a measurable improvement in process throughput for production environments that demand stable, repeatable finishing and semi‑finishing operations.

Precision geometry and secure clamping for consistent results

A square 90° plate form with a 0.8 mm corner radius provides a balance between edge strength and the ability to achieve fine radii on a workpiece. The insert is supplied with a cylindrical hole, ensuring secure and repeatable clamping in compatible ISO holders. Compatibility with a holder depends on the insert’s form, clearance angle, tolerance class, fixation method, size and thickness; these parameters must be matched to the toolholder system to guarantee positional accuracy and cutting stability. The insert’s ISO conformity simplifies holder selection in standard tool setups.

Long‑term economy through reduced tool consumption

The DX140 grade is formulated to deliver very long stand life in aluminium and abrasive non‑metallic workpieces, reducing overall tooling costs despite a higher unit price. The carbide substrate offers the necessary rigidity while the PCD cutting layer resists abrasive wear, which translates into fewer indexings and replacements across production runs. For manufacturers seeking predictable maintenance intervals and lower per‑part tooling cost, the grade’s resistance to abrasion and thermal stability are practical economic advantages.

System considerations and recommended usage

This insert is part of a system comprising an ISO insert, a matching external holder or boring bar, a support pad or clamp set and replacement fastening screws. The plate has a 4.76 mm thickness and a 12 mm size, with a 0° clearance angle specified; these dimensions influence the choice of holder and the achievable depths of cut. Note that the insert is supplied without a chipbreaker, so chip control must be addressed by cutting parameters and holder geometry or by selecting a compatible chipbreaker variant where available. For stable results, choose feed and speed settings appropriate for PCD on aluminium and ensure adequate workpiece clamping.

FAQ

What materials is this insert suitable for? The SNGA120408 DX140 is designed primarily for aluminium and other non‑ferrous metals and abrasive non‑metallic materials, where the PCD grade delivers superior wear resistance.

Does the insert require a special holder? Compatibility depends on the holder matching the insert’s form, clearance angle, tolerance class, fixation method, size and thickness; the SNGA120408 DX140 is ISO‑standard, simplifying selection of a matching ISO toolholder.

How does the absence of a chipbreaker affect machining? As supplied without a chipbreaker, the insert relies on appropriate cutting parameters, toolholder geometry and coolant strategy for chip control; choosing compatible feeds and positive rake holders helps maintain consistent swarf evacuation.

What are the key geometric benefits of the 0.8 mm radius and 90° form? The 0.8 mm corner radius and 90° square form provide a compromise between a robust cutting edge and the capacity to produce defined radii on external profiles, improving edge strength while maintaining finishing capability.

Is the cutting material integrated on a carbide substrate? Yes, the DX140 grade uses a PCD cutting layer on a carbide substrate, combining the abrasive resistance of PCD with the structural support of a carbide body for durable performance.
